UNIVERSAL COUPLING.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed August 3. 1908. Serial No. 1443.518.

To all whom it may concern:

Be it known that I, GEORGE W. (Euro 7 whivh will he of great strength and durability V zl-llLl of simple and rigid construction.

The objects of my in'ontion are zirconiplishorl h} the construction, combination and arrangement of ports described in the following sporificotion, pointed out in tho appended chums zrnd illustru tml in tho accompanying drawings, whoroin similar characters of roferonco rofor to oorrespo ulir v ports throughouttho sororul views, in whic Figure 1 is =1 viow o! on improved univon sol coupling uomplotr. sectional View tukou on tho lino 3-- 2 'l ig. l Fig. 3 is u. transverse soctiouul view taken on the line 3- 53 Fig. l; and Fig. i is o tronsvorso sortionul viou' hilun on tho lino 4-4 Fig. 1.

The forks A arr nuulo of suitable nwtnl having proper resilient quality; each has the hose-portion B which is snitzrhlr bored and provided with a ho moi for thireception of tho sluiits which 1 how dvsignulrd no C rind 1). Each of these forks is nmdo ol' substan- Lizil'nrozi in woos section Hi no in withstand Slllll strain as may ho imposwd rhoroon. hit-rrnul lam-s oi the forlzwnds rvsidv E'no propor dist-alum apart as Lo prruiit proper i-lozrrmu-o lUl Lho m-iulllnbmy movmnoni of rho ring E. This ring is mode of Eliot-ill oi proper quality iLIltl. l'ormed in its pwiplwral hmvqui-distnut from each ot hor are the [our somi-sphoricol doprossions E which will rogisror with similar doprvssions A in tho lorla-onds. The steel bulls l irorido such bearing hotwoen tho ends of tlio forks and tho ring E that, friction between tho memborsis rodurfod to :r minimum and n homing is awomplishcd that will present no surl'occs or 'roooosr-s wherein sodimvnican find. lodgmont. r

G dcsigniito spnn holts Lhv function ol l'ig'. 2 is gr triinsverso Tho which is to resist any tendency of the fork ends to spread under the imposition thereon of unusually hoary strains. Another ad- \ont-ogo :ill'orded h) chose span-bolts is that, the slightest wearing away of the ball joint llHL be compensated for by simply drawing tho fork-ends slightlv closer together by nuinipuhibing the not G. The head G of each is provided with a. recess on its un'de'rside to rooivr the stud A that is secured in the outer face of the fork-ends, whereby rotary movement of tho spomholt is prevented.

A suitable device to lock the nut G in position on the spun-bolt G is shown in Fig. 2 which consists of tho spring clip H countersunk in at shallow channel in thefork-end and sustained hy the rivetor screw B so that when the out G is set in the desired posiiion the (-lip will press against; the hit-oral loco of tho nut and hold it; firmly-in the set position. It is obvious that any suitable. device for locking these nuts may he used.

In the manufacture of my invention the 1 forks are finished to the form subsbsrntially l as shown. and hovo tho depressions properly machined there-in: similar depressions are moohinod in the peripheral face of the ring E To assemble the parts the arms of the fork or" sprung apart suilioiontly to permit i the insertion oi the bolls be'tweon the 'forlc l l 1 ends and the ring; the. balls being in position as indicated, (he span-bolts are Lhon tight.- onod and tho fork-ends nuiy thus be drawn inward each other so precisely as to form and.

ble to nriselnhlo tho ports l) lniud operative means, ii is contoinl'ilzitcd t luitnuiol'iinory for osseiiihliug those parts may he used.

IL will ho roodily understood that proportions in rolorrnoc to the sectional arm of the. shafts through which tho power is being transmitted, that a. con )ling oi grunt strength and rigidity is z'iooomplishod.

While I have shown the central member in tho form of a ring it in obvious that it; may be made as well in lho form oi a; solid disli or olhor form.

Advantages ndditimml to those heretofore :smtcd are that Slight if on lubrication is l needed for theperfoct. operation of my invention' by virtuo of tho )orforations A throu h the 'ori ends and the arrangement of t e for: ends and the. ring E aparbfrom eooh maintain ai-ruo hearing. While it is possitiionod no .diown, the. sortionol area of the .1 respeotn-e port-s are of such ample propor other, the application of the lubricant as may be necessary is facilitated and all tendency of the bearings to become grunnned or clogged is overcome What I claim as my in rention and desire to secure by Letters Patent ol the United States, is

1. A coupling ol' the kind described, coni- )rising a pair of members having oppositely isposed faces, a member disposed between the said member and each of said faces, a

ball bearing: connection between the said member and each of said faces, a member to sustain the opposite faces of each of said pair of members in adjustable position with relerence to each other.

2. A coupling of the kind described, eon1- prising a pair of forked mei'nbers, a central member, a pivotal connection between said central member and each of the forked members includin balls to engage the central member and t e ends of the forked members,

a. device carried byeach forked. member to sustain the opposite faces of each forked 1 ends toward each other and to sustain the member in adjustable position with. reference to each other.

3. A coupling of the kind described comprising a pair of resilient forked members same in dill'erent ad Listed positions substantially as deseriberl l. A coupling ol' the kind described, cone prising a pair 01 resilient forked members having; the fork-ends rmessed upon their inner hires, a central member having recesses upon its face to register with the recesses in the fork-ends, balls to join thel'orleends to said central member and to be seated in the recesses therefor, a span-bolt between the anus of each forked member to draw the said arms toward each other and to sustain the same in difi'erent adjusted positions, substantially as described.

In testimony whereof I sign my name to this specification in the presence of two subscribing Witnesses.
